Uterine Changes Associated With Impaired Fertility in the Dairy Cow

Abstract

Uteri from 55% of a group of repeat breeder cows contained abnormal uterine glands. Morphologically, these glands were characterized by enlargement of the lumen, various degrees of degeneration of the glandular epithelium, and a localized modification of the stoma accompanied by infiltration of either eosinophils or lymphocytes or both. The lesion was localized and was caused by occlusion of the endometrial gland. © 1973, American Dairy Science Association. All rights reserved.
